RESOLVED BY EMPTYING CACHE MANUALLY:

Hi,

I deleted a page attribute Feature value 4 (feature_value_4) about a thousand pages had that attribute and I have not had problems before when deleting a whole attribute, but for some reason this time I cant access the site at all after deleting a attribute.

I'm getting this error no matter where I go on the site:
An unexpected error occurred.
Call to a member function getAttributeKeyHandle() on null

The attribute is being used by some blocks, but I do not understand why the site locks me off the dashboard.

//EDIT: deleted url as it is ip restricted

Any ideas?

Cheers, Petro
